Zinc Provide Maximum Corrosion Resistance


The extensive use of zinc, both as a sacrificial coating on steel and also as a stand-alone material, require a high level of corrosion resistance in order to increase the product life cycle and to avoid ecological pollution by metal ions.

Zinc coatings and castings on steel can be anodized so as to produce a tough and stable coating. The corrosion resistance is said to be superb.

Being used by the military immersed on the subs for high corrosion problem areas such as mooring cleats with good results. A special zinc anodizing handling is available for zinc castings.

This coating is entirely different than that for aluminum alloys.

Anodizing zinc is a practical coating providing maximum corrosion resistance in both atmospheric and marine environments.

As the process uniformly coats deep recess and threaded areas, anodized zinc alloy castings could serve as an economical alternative when replacing traditional bronze, brass and stainless steel components.

Steel items could be fabricated, hot zinc dipped then anodized. The sturdiness of such fittings are said to rival that of stainless steels. Deep scratching does not seem that compromise the durability.

Importance Of Electroplating

Electroplating means deposition of a thin layer of metal to a work piece using an electrolytic process. Electroplating is useful in automotive industry for chrome plating and in electronic industry for optics and sensors. The purpose of electroplating is - appearance, protection, special surface properties and engineering or mechanical properties. All the electroplating finishes are of extremely high quality. Zinc plating, nickel plating, chrome plating and copper plating are just a few examples of CA metal plating chemicals. Nickel coatings have a decorative appearance, corrosion protection, ferromagnetism properties, and wear resistant. The properties of tin coatings are - good appearance, solder ability, nontoxic, corrosion protection, and low friction. The applications of electroplated tin alloys are electronics, semiconductors, food containers, packages, and engine applications. The applications of hard chromium electroplating are industrial rolls, plastic molds, cutting tools,...

Use Of Hard Anodized Aluminum

Anodized aluminum has light weight. It is used mostly for industrial purpose. It is 30% harder than stainless steel. This has a long life span. Even in high heat level the anodized finish will not be damaged because it has a melting point of 1,221 degree f. Aluminum cookware is processed through hard anodized aluminum. It is useful for many industries like automobile industry, commercial cookware, and medical field. This is a bit more expensive than regular anodized aluminum. Anodize can be done at home with the help of sulfuric acid. Hard anodized aluminum is used because it has non toxic finish, cleaned easily, does not wear easily etc. It is available in many colors but mostly black is used. Hard anodized aluminum does not stick on the surface of the cookware. If you have any queries relating to Chicago anodizing chemicals or IL anodizing chemicals just visit our site.

Nickel Plating Chemicals

Nickel has an atomic number of 28. It has 28 protons. The atomic weight of nickel is 58.69, and the chemical symbol is Ni. Nickel is magnetic and does not rust very easily. Nickel is a silver white metal. It is used for many industries like electronics, electroforming and automotive markets. Various benefits of nickel include wear resistance, lubricity, tarnish protection, decorative appearance, surface hardness and corrosion protection. Nickel which is used for engineering purposes is often smooth and dull grey in appearance. These nickel deposits are used for wear resistance, hardness, lubricity and magnetic purposes. Nickel plating chemicals and electro less nickel plating chemicals are available in bright, ultra bright and semi bright. Some products that have nickel in it are rechargeable batteries, coins, welding rods and wires, electronic or computer equipment, and pigments for paints or ceramics, jewellery, kitchen tools and coins. The largest use of nickel is to cast iron a...
